That means that Olivia is, once again, the new kid. Losing her key one day, she meets the first of a number of the building's unusual residents, who turns out to be a ghost. Before the day is over, she has met two mean girls about her age, an old woman whose entire apartment is made of glass, and a budding psychic named Alice.
